An object of the invention is to provide a circuit panel inexpensive to manufacture and which may be used without danger of short circuits.

connections may be conveniently made.,

Another object of the invention 1s to provide a circuit panel having two conducting members insulated from each other by a base, the conducting members being each connected to a plurality of binding posts..

Still another object of the invention is to lprovide a circuit panel having a base oi 1nsulating material in opposite surfaces of which there are sunken portions, one of the conducting members being disposed in each sunken portion and the outer surfaces of the conducting members being covered by insulating material. There are preferablytwosets of binding posts mounted on the base, each set having electrical connections with one of the conducting members.

A further object of the invention is to provide the base with openings in which screws or securing members are disposed and wjliich engage the binding posts for holding them 1n position and each at a conducting member. t

Additional objects of the invention will appear in the following specification in which the preferred form of the invention is described.

In the drawing similar reference-characters refer to similar parts in all the views, of which Figure 1 is a plan'view of the circuit panel, parts being broken away to illustrate the construction,

Figure 2 is an enlarged sectional view on the line 2-2 of Figure 1,

Figure 3 is a sectional vlew on of Figure 1, y

Figure 4 isa sectional view on the line 4-4 of Figure 1, t.

Figure 5 is a perspective view illustrating one of the conducting members and one of the binding posts which engages a terminal of the conducting member, j

Figure 6 is a plan view illustrating a modified form of the invention, and

the line 7-7 the line 3-3 Figure 7 is a sectional view on of Figure 6.

Theconstruction is also such that By referring to the drawing it will be seen that an insulating base 10 is provided, this insulating base 10 having openings 11 vthrough which screws 12 may be disposed,

these screws 12 also preferably passing through openings 13 in the casing 14 and engaging a member 15 by means of which the insulating base 10 will be held in position in the casing and the casing will be held to the member 15.

The insulating base 10 has an inner face 16 and an outer face 17, there being a sunken portion 21 in each of the faces 16 and 17 for receiving conducting members 18. As will be seen by referring to Figure 5 of the drawing, each conducting member 18 has arms 19 disposed substantially at right angles to each other, there being an angular opening 2O adjacent the terminal of each of the arms 19. The sunken portions 21 in thevfaces 16 and 17 of the insulating base 10 are of the ysame general configuration as the conducting members 18, so that the conducting members 18 may be disposed in the sunken portions 21 of the insulating base 10. However, the arms of one of the sunken portions 21 are staggered relatively to the arms of the other sunken portions 21 so that the arms of one ofthe conducting members 18 will be staggered relativelyfto the arms of the other conducting member. When the conducting members 18 are disposed in the sunken portions 21 of the insulating base 10, the outer face of the conducting members 18 are coated with an insulating substance, such as insulating wax 22. y

In the insulating base 10 there are two sets of openings 23 and 24 for receiving the binding posts 25 and 26, the openings 23 extending a suflicient distance to permit the angular terminals 27 of the binding posts 25 to fit in the angular openings 20 in the arms 19 of the outer conducting member 18, while the openings 24.in the insulating base 10 extend a sutlicent distance to permit the angular terminals 27 of the longer binding post 26 to fit in the angular openings 20 on the arms 19 of the inner conducting member 18. Be'- cause of the engagement of the angular terminals 27 of the binding posts withV the terminals 19 of the conducting members 18 at their angular openings 20 the binding posts are prevented from rotating relatively to the insulating base 10.

There are apertures 28 in the insulating base l0 which lead to the-openings 23 and in these apertures 28 there are screws 29 which have heads 30 engaging shoulders 31 on the insulating base and which have threaded ends 32 which mesh in threaded orifices 33 in the binding posts 25. By this means the bindin posts are held in position, not only with reerence to the insulating base 10, but also in contact with the outer conducting member 18. The binding posts may, of course, be of any desired construction. The longer binding posts 26 are provided with angular terminals 27 which fit in the angular openings 2O in the arms 19 of the inner conducting member 18, it being possible to provide similar means for securing the binding post 26 totheinner conducting member 18.

Inasmuch as the arms 19 of one of the conducting members 18 are staggered relatively to the arms of the other conducting member 18.y it will be understood that each alternate binding post will be connected with one of the conducting members 18, while the remaining binding posts will be connected with the other conducting member 18 and that, therefore, when two companion binding posts are connected with an incoming current, the other companion binding posts may be connected to leads running to fixtures of any desired type.

An insulating cap 34 is provided which is normally disposed over the insulating base 10 and which has a plurality of openings 35, one for receiving each binding post. In this way it is possible to insulate the binding posts from each other after the proper connections have been made. Preferably the cap 34 is secured to the insulating base 10 by means of screws 36 which are disposed in orifices 37 in the cap 34 and in orifices 38 in the insulating base 10 and which'have threads which mesh with threads on nuts 39 which are disposed in cavities 40in the insulating base, the nuts 39 being covered by an insulatingmember 41 at the outer portions of the cav1t1es. lj

In the modified form of the invention illustrated in Figures 6 and 7, the insulating base 42 has an inner sunken portion 43 and an outersunken portion 44, these sunken portions 43 and 44 being preferably disposed at right angles to each other, there being a conducting member 45 disposed in the sunken portion 43 and a conducting member 46 disposed in the sunken portion 44, these conducting members 45 and 46 being covered at their outer sides by insulating material 47. The conducting member 45 is connected to two plates 48 at the outer face of the insulating base 42 by means of screws 49 which are disposed in orifices in the conducting' mem-v ber 45 and which mesh in threaded openings in the plates 48. The conducting member 46 is also connected with two plates 50 4and the said plates 50 are preferably held inengagpment with the conducting member 46 y means of screws 51 which are disposed in the openings in the plates 50 and mesh with threaded orifices in the conducting members 46. It will be understood that binding posts secured to adjacent plates 48 and 50 may be used to complete the circuits in the customary manner. The insulating base 42 is preferably secured to a casing similar to the casin 14 by means of screws which may be dispose in openings 52 in the insulating base 42 and which may extend through o enings 13 in the casing 14.and into a mem er similar to the member 15.

What is claimed is In a circuit panel, an insulating base having opposite faces each with a sunken portion, there being two sets of openings in the base extending throughone of the said faces, one set of openings ending to each sunken portion, there being apertures extending from the other face of the base to certain of the openings, two conducting members each with terminals extending at angles to each other, there being non-circular o ings in the terminals, one of the conducting members being disposed in each `sunken portion of the base with its non-circular openings at the base opening and with the terminals of one conducting member staggered with reference to the terminals of the other conducting member, binding osts in the base openings having non-circular portions fitting the non-circular o nings in the conductin members, all the Ibinding posts extending beyond one face of the base, and means in the apertures for holding binding posts in lace.
